Education
Research assistant, part-time PhD, Bioinformatics
University College London
London, UK
Present - 2017
- Thesis: Using transcriptomics to improve the diagnosis rate of rare disease patients.
- Ultimately, the goal of my PhD is to develop and apply statisical methods and software that improve the genetic diagnosis rate using RNA-sequencing. This involves detection of aberrant RNA-level events when complemented with, DNA sequencing help to resolve variants of unknown significance.
